Kima joins Mastercard sandbox to enable stablecoin card top-ups

Kima, a decentralized settlement protocol, has integrated into Mastercard’s sandbox program, facilitating stablecoin-powered top-ups for prepaid cards directly from self-custody wallets. This integration allows Mastercard partners to leverage Kima’s infrastructure for topping up prepaid cards using stablecoins like USDC and USDT from self-custody wallets across over 10 blockchains. Kima CEO Eitan Katz highlights this as a significant step towards mainstream stablecoin adoption, streamlining crypto-to-fiat conversions and enhancing crypto usability.

Kima’s asset-agnostic settlement system simplifies cross-ecosystem payments, supporting various systems including public blockchains, private ledgers, and traditional banking rails. This aligns with Mastercard’s goal of integrating stablecoins into mainstream finance. Katz emphasizes the need for seamless coexistence between crypto and fiat currencies to unlock their full potential, rejecting the notion of crypto as a replacement for fiat.

Kima’s solution offers cross-chain interoperability, eliminating intermediaries and complex smart contracts. This enhances security and efficiency. Furthermore, Kima’s involvement with the European Central Bank (ECB)’s digital euro initiative underscores its role in shaping the future of digital finance. Kima is among 70 private sector partners collaborating with the ECB on exploring digital euro functionalities.

Despite its institutional partnerships, Kima prioritizes user control and data privacy. Know-Your-Customer (KYC) and Anti-Money Laundering (AML) checks are handled by third-party banks and virtual asset service providers during onboarding; Kima does not access user data. Every transaction includes immutable metadata tags verified by Kima’s protocol-level engine against local regulations, ensuring compliance with various global standards. Users maintain complete control of their keys, while cryptographic proofs facilitate compliance. This approach offers institutions a user-friendly control layer while preserving true self-custody for users. The integration showcases a shift in the crypto landscape, with stablecoins increasingly bridging the gap between traditional finance and decentralized systems.
